  • Illegal mix of collations error after moving to new server

    Have exact same problems as others here on the forum, after moving to a new server!

    I get a lot of error message e-mails like the one below:

    Code:
    Database error in vBulletin 5.1.4:
     
                      Invalid SQL:

    I tried the script which was posted for a 3.8.2 and up to 4.2 board, but it can't run with VBulletin 5!

    Anyone has a similar script that just work for VB 5? The below is for VB 3.8.2

    PHP Code:
      <?php // Don't forget to enter your db infos.  define('THIS_SCRIPT', 'convert'); require './global.php';  //---------------  header('Content-type: text/plain');  $dbconn = mysql_connect('localhost', 'DB-user', 'DB-pass') or die( mysql_error() ); mysql_select_db("db_name");  $sql = "ALTER DATABASE `DB-Name` DEFAULT CHARACTER SET latin1 COLLATE latin1_general_ci"; $result = mysql_query($sql) or die( mysql_error() ); print "Database changed to latin\n";  $sql = 'SHOW TABLES'; $result = mysql_query($sql) or die( mysql_error() );  while ( $row = mysql_fetch_row($result) ) { $table = mysql_real_escape_string($row[0]); $sql = "ALTER TABLE $table DEFAULT CHARACTER SET latin1 COLLATE latin1_general_ci, CONVERT TO CHARACTER SET latin1 COLLATE latin1_general_ci"; mysql_query($sql) or die( mysql_error() ); print "$table changed to latin.\n"; }  mysql_close($dbconn); ?>

        I have seen this happen in 4.x when one or more of the database tables have different collation sequence definitions. The error occurs in a SQL query where the query is trying to UNION two subqueries and one of the tables in the subquery has a different collation sequence than the other tables involved in the query.

        If you have access to the database, you can run SHOW TABLE STATUS; to display details for all of the tables. Check the collation sequence column to find the ones that differ.

          When you moved to the new server, your database settings weren't preserved. You'd need correct the tables/columns to have the same encoding as the rest of the database.

            Thanks for the hint ZFI, they are ALL "latin1_swedish_ci" so will I have to change something somwhere now?

            In Language & Phrases -> Language Manager -> HTML Character Set is set to: ISO-8859-1 is that correct?

              Thank you, what tables/columns are we speaking, can you please be more specific?

                No, I'm not sure which tables/columns are the problem, the database error isn't 100% clear. But ALL of the tables in the database should match.

                  As I already wrote, the one in the "collation" do all match. Are there other tables/columns that have to match with something ? if so, which one please?

                  Is there any other way to get a better "error" so you may know what is wrong?

                    If all tables and all columns did match, you wouldn't be getting the error message.

                      Okay.. which tables do I have to check then and which fields, would you be so kind and be more specific please?

                      I run this: SHOW TABLE STATUS and it shows all the tables and fields, I assume.

                      Then I checked the collation sequence column

                      There all the way down it says: latin1_swedish_ci

                      So I would appreciate it much if you could let me know what other columns I have to check? From a Google search it seems I'm not the only one that have problems with it

                        Okay I made another Google search, and it seems there is something more complicated that has to be done:

                        When I run this command: show variables like 'collation%'

                        I get the below output:
                        collation_connection utf8mb4_general_ci
                        collation_database latin1_swedish_ci
                        collation_server utf8_general_ci
                        So I guess that's where the problems start right?

                        I read the below, does this apply for this error as well:
                        The utf8_general_ci collation will do but ideally we want utf8_unicode_ci. The former basically ignores all accents: it treats ‘ü’ the same as ‘u’. The latter pays attention to accents; it’s a tiny bit slower but more accurate.

                          Again, is every single table, and column in the ENTIRE database, set to the correct/same setting as every other one?

                          • #14
                            What is the correct same setting?

                            From your replies it seems you don't want to help.

                            Otherwise I think we can agree that if I enter the SQL command " SHOW TABLE STATUS " then it should pull up ALL tables in the entire database for vbulletin right?

                            So, and if I go to the column " Collation " which is the only column I can find there where you have encoding parameters and the whole row down it says :
                            latin1_swedish_ci
                            Then I assume we can agree that it all is OK.. is there any other SQL command I should run and any other culumn I should check? If so, would you be so kind and spend 2 sec. to tell me that?

                            There is another Table "Datatype" there it sometimes changes from MyISAM to InnoDB - can this be an error maybe?
